The Microsoft Active Directory schema contains formal definitions of every object class that can be created in an Active Directory forest. The schema also contains formal definitions of every attribute that can exist in an Active Directory object. This section provides the reference for each schema object and provides a brief explanation of the attributes, classes, and other objects that make up the Active Directory schema.

In each of the reference topics, there is a section for each operating system that the topic applies to. The following operating systems are currently supported.

Platform

Name in topic

Microsoft Windows Server 2003

Windows Server 2003

Microsoft Active Directory Application Mode (ADAM)

ADAM

Microsoft Windows Server 2003 R2

Windows Server 2003 R2

Microsoft Windows Server 2008

Microsoft Windows Server 2008

Microsoft Windows Server 2008 R2

Microsoft Windows Server 2008 R2

Microsoft Windows Server 2012

Microsoft Windows Server 2012

If an operating system is not listed in the topic, the topic is not supported on that operating system. For example, if a topic only lists Windows Server 2003 and ADAM, then the topic does not apply to Windows Server 2003 R2.

The following sections contain detailed information about the Active Directory schema elements.
